A colorful tome with more drawings than text.
It is a children's fairytale, based on Emissary and Draconiz, called The Rainbow Pseudo-Dragon, about how Emissary created a friend, a big scary dragon because he had no friends, and then the two became the best of friends, but eventually, they had falling out and they got in a fight, and the dragon he created punched him so hard he flew across the world.
The moral of the story, if one was to try really hard to find one, seems either to be not to force friendships or to treat friends nicely. It's hard to tell.
